Assignment 4 v0.07 and v0.071

The reason why there's two is because I found out I was editing v0.06
and not sure if I had changed anything from the previous v0.06 and v0.07
I decided to make a new one and copy my edited v0.06 to it. This one
adds animations to the Ground Enemies and Air Enemies. All the art is
hand drawn by me!
